The Omron E3JKRR112MOMI is a retro-reflective photoelectric sensor with a relay output rated for 3 A at 24-240 VAC/DC, meaning it can switch small contactors or motor starters directly without an interposing relay. The 11 m sensing range covers most conveyor and gantry applications, but the 20 ms response time is too slow for high-speed counting or fast object detection.
The 50 x 50 x 18 mm housing mounts via two through-holes on 25 mm centers or a separate bracket (not included). The 2 m PVC cable exits the rear; wire as per nameplate: typically brown/blue for supply (24-240 VAC/DC), black and white for relay contacts (NO/NC, common). Light-ON/Dark-ON is selectable via a DIP switch under the lid – no need to swap wires. IP64 means it's dust-tight and splash-proof, suitable for indoor or covered outdoor use within -25 to 55 °C. No special derating needed up to the listed 3 A relay load at 240 VAC.
